y = mx + b, where m = slope, and b = y-intercept.
Since you are not given the y-intercept, you have to solve for it through the equation, y = (4/5)x (which is the slope you are given) + b, and replace x and y with values given, which are (-5,-3)
y = (4/5)x + b
-3 = (4/5)(-5) + b
-3 = -4 + b
1 = b
Then replace b in the first equation to get the answer
y = (4/5)x + 1
Now we have a negative exponent, which is the opposite of a positive exponent.
If a positive exponent means you're multiplying by 10s and it makes a number bigger by moving the decimal to the right, then
the opposite of this is that a negative exponent means you're dividing by 10s and making the number smaller by moving the decimal point to the left.
Examples:


The trick is to recognize that
is the same thing as 
and
mean the same thing.
So, 
For your exercise,
means you'll move the decimal point 24 places to the left, to make the number smaller.
To solve this problem you must find 86% of 19,396.
To do this, let's start by turning 86% a decimal to multiply.
86% will become 0.86
Now, we multiply 0.86 by 19,396.
We get the answer, 16680.56
The question says about, so we need to round it.
When rounded we get 16681.
That means 16681 bulldogs were registered in 2003.
Hope this helped you! :)
